Contains information about a single instance of a Binding.
Assembly: PresentationFramework (in PresentationFramework.dll)
The Binding class is the high-level class for the declaration of a binding. The class is the underlying object that maintains the connection between the binding source and the binding target. A Binding contains all the information that can be shared across several objects. A is an instance expression that cannot be shared and that contains all the instance information about the Binding.
For example, consider the following, where myDataObject is an instance of the MyData class, myBinding is the source Binding object, and MyData class is a defined class that contains a string property named MyDataProperty. This example binds the text content of mytext, which is an instance of TextBlock, to MyDataProperty.
You can use the same myBinding object to create other bindings. For example, you might use the myBinding object to bind the text content of a check box to MyDataProperty. In that scenario, there will be two instances of that share the myBinding object.
This example shows how to obtain the binding object from a data-bound target property.
You can do the following to get the Binding object:
You must specify the dependency property for the binding you want because it is possible that more than one property of the target object is using data binding.
Alternatively, you can get the and then get the value of the ParentBinding property.
For the complete example see Binding Validation Sample.
If your binding is a MultiBinding, use BindingOperations.GetMultiBinding. If it is a PriorityBinding, use BindingOperations.GetPriorityBinding. If you are uncertain whether the target property is bound using a Binding, a MultiBinding, or a PriorityBinding, you can use BindingOperations.GetBindingBase.
